Latest Patents
One of Ki-Min Lee's latest patents is a method of manufacturing a thin film capacitor. This innovative approach involves forming a first electrode layer with protrusions and depressions on its surface, followed by the application of a sacrificial layer that is reflowable when heated. After heat treatment, the sacrificial layer and first electrode layer are etched to create curved protrusions, allowing for the formation of a dielectric layer and a second electrode layer. This method enables the production of thin film capacitors with higher capacitance without increasing the electrode area.
Another notable patent is a method of manufacturing a semiconductor device with triple gate insulating layers. This invention aims to simplify the process of obtaining optimal thicknesses and qualities for gate insulating layers across multiple devices. By utilizing dummy gates, Lee's method allows for the easy formation of gate insulating layers tailored to the specific requirements of each transistor. This innovation facilitates the manufacturing of high integration density devices, as it enables finer line widths for gates in high and middle voltage regions compared to those in low voltage regions.
